    The objective of this retrospective study was to evaluate Stage IIIA endometrioid type endometrial carcinomas (ECCs) and to analyze clinical and pathological determinants of prognosis in three tertiary hospitals between January 2007 and January 2017. Forty-seven patients with a median age of 61 (range: 31 to 76) years were diagnosed with Stage IIIA disease. Median follow-up was 45 (range: 6 to 116) months. The five-year disease-free survival (DFS) rate was 57.2%, and the overall survival (OS) rate was 59.7%. In the univariate analysis, age and grade of the disease (1-2 versus 3) disease were found to be significant factors for DFS. Univariate analysis also revealed the presence of cervical stromal involvement and grade of the disease were associated with decreased OS. In the multivariate analysis, however, only patients with an advanced histological grade had a reduced risk for OS (hazard ratio [FIR] 2.9; 95% confidence interval [CI] 1.020-8.615; p= 0.040). In conclusion, histological grade seems to be an independent prognostic factor for OS in patients with Stage IIIA ECCs.

    Correlation of Clinical Risk Factors with Diffusion-Weighted Magnetic Resonance Images in Prostate Cancer Patients Treated with Definitive Radiotherapy
    (2015) Erbay, Gurcan; Onal, Cem; Guler, Ozan C.; Karadeli, Elif; Koc, Zafer
    This study is aimed to correlate apparent diffusion coefficient (ADC) values and clinical T-stage, serum PSA, pathology Gleason scores. We also further analyzed whether ADC values could be used to appropriately define the risk groups. 135 biopsy-proven, radiotherapy-(RT)-treated, prostate cancer patients who underwent pre-RT DW-MRI and standard T2W pelvic MRI were included. ADC and normalized ADC (nADC) values were calculated from DW-MRI delivered a median 8.1 weeks after prostate biopsy. ADC values were correlated with clinical risk factor values by using Pearson correlation test. ADCs in low-, intermediate-, and high-risk patients were 0.873 +/- 0.122X10(-3) mm(2)/s, 0.763 +/- 0.124X10(-3) mm(2)/s, and 0.701 +/- 0.132X10(-3) mm(2)/s (p = 0.001), respectively. Patients with preRT PSA <10 ng/mL had significantly higher ADCs than patients with preRT PSA 10-20 ng/mL (p = 0.02) or >20 ng/mL (p < 0.001). Mean ADC for patients with Gleason score <7 was significantly higher than patients scoring 7 (p = 0.001) or >7 (p < 0.001). Clinical stage
